Erlang/OTP 19.0 has been released
--------------------------------------------------

Erlang/OTP 19.0 is a new major release with new features, quite a few
(characteristics) improvements, as well as a few incompatibilities.

Some highlights of the release are:


   - *compiler, stdlib*:
   - New preprocessor macros *?FUNCTION_NAME, ?FUNCTION_ARITY*
      - New preprocessor directives -error(Term) and -warning(Term) to
      cause a compilation error or warning, respectively.


   - *gen_statem* a new state machine behavior
   - *mnesia_ext*: plugin of external storage solutions to mnesia
   - *crypto*: uses EVP interface in OpenSSL resulting in generally better
   performance and support for HW acceleration
   - *ssh*: performance improvements, uses the new gen_statem behavior
   - *ssl*: enhanced error log messages
   - *dialyzer*: the support for maps is very much extended both the type
   specification syntax and the type analysis.
   - *erts*:
   - erlang:open_port(spawn, ...) 3-5 times faster
      - tracing, extensive improvements (scalability, speed, match
      specifications on send/receive, support for lttng, ...)
      - dirty schedulers improved
      - per process configurable handling of message_queue
      - fast loading of multiple modules
      - max_heap_size process flag
   - *erts/kernel:*
      - Experimental support for Unix Domain Sockets
      Example: gen_udp:open(0, [{ifaddr,{local,"/tmp/socket"}}])
   - and much more ....
